Macherey-Nagel Chromafil disposable syringe filters are designed for reliable filtration of suspended matter from liquid samples. Featuring polyester (PET) membranes with integrated glass fibre prefilters (GF/PET), they are ideal for aqueous, polar, and non-polar solvent solutions. Certified for HPLC applications, they ensure reproducibility, solvent compatibility, and efficient sample preparation for high particulate or viscous samples.
Product Features
- Used for filtration of suspended matter from liquid samples
- HPLC certification available online
- Polypropylene housing with better solvent stability than acrylate or polystyrene
- Shells ultrasonically sealed, not glued – no extractable glue components
- Allows filtration in both directions; liquid cannot bypass the membranes
- Luer lock on entry side ensures safe connection for high-pressure use
- Luer exit: standard luer for 3 mm and 25 mm filters, minispike luer with low dead volume for 15 mm filters
- Deflector breaks and distributes liquid stream to prevent membrane rupture
- Star-shaped distribution device ensures full membrane use, prevents clogging, and improves flow efficiency
- Colour-coded housings: 0.2 µm = yellow, 0.45 µm = colourless; membrane types differentiated by housing colour
- Low dead volume: ~80 µl (25 mm), 35 µl (15 mm), 5 µl (3 mm)
- Chromafil Xtra: plain polypropylene housing labelled for method validation and certification
- Imprint identifies membrane type, diameter, and pore size
- Hydrophilic membrane suitable for polar and non-polar solvents
- Polyester filter with integrated glass fibre prefilter recommended for high particulate or viscous solutions
- Autoclavable at 121°C and 1.1 bar for 30 minutes
- Filter diameter: 25 mm
- Pore size: 0.45 µm
- Pack quantity: 100 filters
